What would happen to the rate of photosynthesis in C₃-plants if CO₂ concentration level almost doubles from its present level in the atmosphere?

Which photosystem will work if only longer wavelengths of light are given to a plant ?

Mention the four basic requirements for chemiosmosis to occur.

Mention any two reasons, which prove that photosynthesis is essential for sustaining life on the earth.

Why is the colour of a leaf kept in the dark frequently yellow, or pale green? Which pigment do you think is more stable?

(ii) What are A, B and C?
(iii) At what stages ATP is converted into ADP?

Give comparison between the cyclic and non-cyclic photophosphorylation.

Six turns of Calvin cycle are required to generate one mole of glucose. Explain.

In the figure given below, the black line (upper) indicates action spectrum for photosynthesis and the lighter line (lower) indicates the absorption spectrum of chlorophyll-a, answer
the following.
(i) What does the action spectrum indicate?
How can we plot an action spectrum?
Explain with an example.
(ii) How can we derive an absorption spectrum for any substance?
(iii) If chlorophyll-a is responsible for light reaction of photosynthesis, why do the action spectrum and absorption spectrum not overlap?
